CASTER-SOCKET.

SPECIFICATION forming part of Letters Patent No. 685,07 3, dated October22, 1901. Application filed March 18. 1901. Serial No. 51,664. (Nomodel.)

use and at the same time to provide a simple,

inexpensive, and durable socket.

To this end the invention may be said briefly to consist in constructinga castersocket from a single strip of metal bent to form top and bottombracing cross-pieces'and resilient sides. This frame in thefailly-developed embodiment of my invention is constructed from a singlepiece o f' metal comprising top and bottom cross=pieees and side piecesand a pair of resilient wings to bear upon the interior of the/openingin the end of the bedstead or other l g, while the end pi ces of theframe have a tube set therein With a resilient ca ch to hold the caster,and a washer is formed to set within the frame and be held an carriedthereby.

F01 full OOmprehenSion, however, of my invention reference must be hadto the accompanymg rawings, forming a part of this speeifiea ion inwhich like symbols indicate the same parts, and wherein- Figure 1 5aside elevation of my improved Sock Wi Pa caster in place. Fig. 2 is also& l e e evation thereof, but the view is taken t r g gles to thedirection from which Fig. 1 iS t ken; Fig. 3 is a top View of the socketwith caster in place and with the resilient parts f i"retaining thecaster sprung open. to release rt. Fig. 4 is a detail view of the stripfrom which the socket-frame is bent. Fig. 5 IS a etail View of the tubefor receiving the s e j spindle. Fig. 6 is a detail view of the Washer,and Fig. 7 is a perspective View of y iitame alone without its auxiliaryresilient ret aining devices.

,lThe frame of my improved socket consists 92 a metallic strip bent toform the bottom cross-piece b, top cross-piece 0, side pieces cl fl ndd, and resilient Wings e, integral with the top cross-piece 0, each ofthe said top and spun, as at 11, over the edge of said opening to secureit rigidly in place. The upper end of this tube projects a shortdistance through the opening in the top cross-piece and is slotted, asat j, to forniresilient fingers 7r, while the edgeof the opening in saidtopCross-piece is provided with a series of inwardly-projectin'g teat-sZ, which take into the slots j and serve the double purpose of securingthe tube against longitudinal displacement and of relievin g theresilient fingers t' of the lateral pressure of the caster-spindle m. v

The washer, which is set in place before the tube, consists of a disk11, centrally perforated, as at 0, and cut away at diametricallyopposite sides, as at p, to straddle the side.

pieces d and d of the frame.

When my improved socket is set in place in the usual opening in thebedstead or other leg, the resilient wings e and the sides at will bearupon the walls of said opening and retain the socket againstdisplacement, and

when the spindlem of the c'asteris thrust home the knob or head gthereof will force the resilient fingers apart and pass them and whenthe bedstead is lifted will be supported on the tops thereof.

If desired to supply the demand for an inexpensive and simple socket,the frame alone can be used, as shown in Fig. 7, without the tube andresilientwings and with or without the washer. In such a case theresilient sides alone will retain the socket against displacement, whileof course if the article of furniture which the caster supports islifted said caster will fall from place.

What I claim is as follows:

1. A caster-socket blank consisting of a strip of metal having twostraight portions constituting the sides of the socket and of even widththroughout their length; a perforated portion between and of greaterwidth than said straight portions; a perforated portion at the end ofone of the straight portions; and the opposite ends of said blank beingformed respectively with a notch and tongue, substantially as described.

2. A caster socket made from a single length of metal and consisting oftop and bottom perforated cross-pieces, and resilient side pieces,saidtop cross-piece being integral with one end of each of said resilientside pieces, and one side edge of said bottom cross-piece beingintegralwith the opposite end of one of said resilient side pieces; the free endof the other side piece terminating at the adjacent free edge of thebottom cross-piece; and means limiting the movement of the end of saidfree side piece toward the other side piece substantially as describedand for the purpose set forth.

3. A caster socket made from a single length of metal and consisting oftop and bottom perforated cross-pieces and resilient side pieces,saidtop cross-piece being integral with one end of each of said resilientside pieces, one side edge of said bottom cross-piece being integralwith the opposite end of one of said resilient side pieces, the oppositeside edge of said bottom cross-piece being slotted and the free end ofthe other resilient side piece being formed with a lug substantially asdescribed and for the purpose set forth.

4. A castersocket made" from a single length of metal and consisting oftop and bot tom perforated cross -pieces, resilient side pieces andlaterally-bearii'ig resilient wings in one piece With said topcross-piece, substantially as described and for the purpose set forth,

5. A caster -socket made from a single length of metal and consisting oftop and bottom perforated cross-pieces, resilient side pieces andlaterally-bearing resilient Wings in one piece with diametricallyopposite sides of said top cross-piece, substantially as described andfor the purpose set forth.

6. A castersocket made from a single length of metal and consisting oftop and bottom perforated cross-pieces, resilient side pieces andlaterally-bearing resilient wings in one piece with diametricallyopposite sides of said top cross-piece, said top cross-piece beingintegral with one end of each of said resilient side pieces, and oneside edge of said bottom cross-piece being integral with the oppositeend of one of said resilient side pieces, substantially as described andfor the purpose set forth. 1

7. A caster socket made from a single length of metal and consisting oftop and bottom perforated cross-pieces, resilient side pieces andlaterally-bearing resilient wings integral with diametrically oppositesides of said top cross-piece, said top cross-piece being integral withone end of each of said resilient side pieces, one side edge of saidbottom cross-piece being integral with the opposite end of one of saidresilient side pieces, the opposite side edge of said bottom crosspiecebeing slotted and the free end of the other resilient side piece beingformed with a tongue,substantially as described and for the purpose setforth.

8. A caster socket made from a single length of metal and consisting oftop and bottom perforated cross-pieces, and resilient side pieces, thetop cross-piece having a series of teats projecting into the perforationtherein, and a tube having resilient fingers at its upper end, said tubebeing rigidly connected at its lower end to the edge of the perforationin the bottom cross-piece and having its upper end projectingia shortdistance through the perforation in the top cross-piece, with said teatsprojecting between said resilient fingers, substantially as describedand for the purpose set forth.
